Structural & Manufacturing Specification Summary

Quick Default Download: ↓ .DXF ↓ .SVG ↓ .PDF

A laser-cut finger-joint box (also known as a press-fit or box-joint enclosure) interlocks 5 or 6 flat panels of plywood, MDF, or acrylic using alternating rectangular tabs and slots whose depth equals the exact sheet thickness (T). Standard generators fail in real workshops because the laser beam vaporizes a kerf channel (typically 0.10mm to 0.20mm wide), leaving joints loose and wobbly. Our parametric engine computes odd-numbered symmetric finger counts along every edge and offsets male tabs by +Kerf/2 while narrowing female slots by -Kerf/2 to guarantee an airtight friction snap-fit without clamps.

Structural Geometry & Allowances

Mathematical Blank & Tolerance Formulas

Symmetric Odd Finger Count (N_fingers)

N_fingers = 2 * round( (Edge_Length / Target_Tab_Width - 1) / 2 ) + 1

Forces an odd number of segments along every edge so both corners terminate identically for maximum structural rigidity.

Kerf-Compensated Male Tab Width (W_tab)

W_tab = (Edge_Length / N_fingers) + Kerf

Expands male fingers by the laser kerf width (K) so the remaining wood after laser vaporization equals the exact slot width.

Tab Protrusion Depth (D_tab)

D_tab = T (Exact Caliper Material Thickness)

Matches the mating sheet's true caliper thickness so outer corners sit 100% flush.

Pre-Press & Production SOP

Step-by-Step Export & Assembly Guide

1 Measure your plywood or acrylic sheet in 3 places with a digital caliper and enter the exact average in Material Thickness (T)—never trust nominal '3mm' without measuring.
2 Enter your machine's Laser Kerf (K): use 0.12mm for a tight wood snap-fit, 0.08mm for a light glue fit, or run our Kerf Calibration Strip Generator first.
3 Check the 6 nested panels (Base, Top Lid, 2 Front/Back Walls, 2 Left/Right Walls) in the 2D CAD view and test the 3D Assembly Slider.
4 Uncheck 'Include Dimensions Layer' and export as 1:1 .DXF (for LightBurn / AutoCAD) or .SVG (for Glowforge / xTool Creative Space).

Packaging & CNC Engineering FAQ

Frequently Asked Questions — Laser Finger-Joint Box

Why are my laser-cut finger joints either too loose or too tight?

Two variables control joint tightness: Material Thickness (T) controls how far the fingers stick out at the corners, while Laser Kerf (K) controls how tightly the fingers squeeze sideways into the slots. If the fingers stick out past the face, decrease T. If the box falls apart without glue, increase Kerf by +0.03mm.

What kerf setting should I use for Glowforge or xTool on 3mm plywood?

On a standard Glowforge Basic/Pro or xTool P2/S1 cutting 3mm Baltic Birch plywood, the beam kerf is approximately 0.14mm to 0.16mm. Entering K = 0.12mm produces a firm press-fit that taps together with a rubber mallet.

Does this generator create duplicate overlapping lines between panels?

Never. Each of the 6 panels is laid out with a clean 6mm nesting gap as an independent, 100% closed polyline so your laser cuts each perimeter exactly once without double-burning.

Can I cut this finger-joint box on a CNC router instead of a laser?

Yes. For CNC routing with a cylindrical endmill (e.g., 1/8" / 3.175mm bit), set Kerf to 0.00mm in our generator so the DXF outputs true nominal geometry, and add 'Dogbone' corner fillets inside your CAM software (Vectric VCarve or Fusion 360) for the inside corners.
